Garden produce

Bloom was a great deal and we had amazing results! Our flowers were much bigger and brighter; our garden was the most productive we’ve ever had too. We were blown away by the results compared to prior years – our tomatoes outgrew every cage we built around them and the squash took over our yard! We will definitely order again and use it in the rest of our yard.

Awesome experience working with Bloom! This was my third attempt to grow grass in my very shady backyard with bad soil. I needed to plant special dense shade grass seed in very poor soil and Bloom, sand, and sawdust. The mix was easy to spread and not clumpy. The grass is as thick as carpet and very deep green. It’s incredible!
